M-ACHINEFOR MAKING TILES. y

SPECIFICATION forming part of Letters Patent No. 686,656, dated November12, 1901.

Application filed February 8, 1899. Serial No. 704,883. (No model.)

To all whom it may concern:

Be it known that 1, ANDREW J. HOBAN, of St. Paul, Ramsey county,Minnesota, have invented certain Improvements in Machines for MakingTiles, of which the following is a specification.

My invention relates to improvements in machines for making tile forsidewalks, &c.; and it consists in the. construction and arrangementhereinafter particular] y described and claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a top elevation of my improved machine. Fig. 2 is a similar viewwith the upper framework removed. Fig. 3 is a section on line A A ofFig. 2. Fig. 1 isa section on line B B of Fig. 2. Fig. 5 is a section online C G of Fig. 2. Fig. 6 is a section on lineD D of Fig. 2. Fig. 7 isa section on line E E of Fig. 2. Fig. 8 is a section on line F F of Fig.2. Fig. 9 is a section on line G G of Fig. 2. Figs. 10 and 11 arepartial views of the carrying platform or table. Figs. 12, 13, and 14are vertical sections through the feeding and mixing apparatus. Fig. 15is a section on line 7 7 of Fig. 7. Fig. 16 is an end view ofbottom-feeding mechanism, and Fig. 17 is a vertical section of the same.

In the drawings, A represents the framework, which is provided with astationary elevated ring or table 2. Arranged upon the stationary table2 is a rotatable ring or table 3, connected by spokes 1 with a verticalshaft 5. Upon theupperend of the vertical shaft 5 is mounted aseven-toothed gear 6, which is engaged and driven by a tooth 7,laterally offset from a gear 8, the gear 8 being engaged with and drivenby worm-gear 9 upon the main driving-shaft 10. The operating-table 3 isformed with a moldopening 11, in which a mixture is placed and actedupon to form a tile. The mechanism for carrying out the steps of themanufacture (which will be hereinafter specifically described) areactuated by cams mounted upon ahollow vertical shaft 12, driven from themain driving-shaft through the medium of the gears 13 and 14.. It willbe noted that the teeth upon said gears are in the ratio of sixteenteeth upon the gear 14 to fourteen upon gear 13. This causes the shaft12 to be operated through one andv one-seventh revolutions while theshaft 5 is being actuated by the cam 7 to turn the table throughone-seventh revolution, thus keeping cam-shaft even with table.

There are shown in the drawings seven independent means for making thetile: first,

the means for feeding the bottoms to the mold; second, for feedinga-mixture into the mold; third, for compressing the mixture; fourth, forfeeding a second mixture; fifth, for compressing the same into and uponthe first mixture; sixth, for troweling and scraping, and, seventh,means for removing the finished tile and bottom. Y

Figs. 3, 15, 16, and 17 show the board-feed ing means. In the positionshown in Fig. 3 the mold-opening through the operating-table isregistering with a similar opening 15 in the stationary platform 2.Underneath said opening is a slidable support 16. This support is raisedand lowered to carry bottoms into the mold by means of a lever-arm 17,fulcrumed upon the horizontal shaft 18 and connected at its power end byrod 19 to the end of the lever 20, the opposite end of the lever beingactuated by a cam 21, carried by the camshaft 12. ..Arranged outside ofthe operating-table is a receptacle 22, adapted to hold a series oftile-bottoms 23. The bottom of the receptacle is closed by a slide 2 1,provided with a toothed rack 25, with which engages a toothed segment26, having pivotal support 27. The segment 26 is turned to carry theslide 24 to the rear of the receptacle by means of a rod 28, connectingthe segment with an arm 29, having upon its end a clutch 30, slidableupon the shaft 18. The clutch member 30 is adapted to be thrown intocontact with a clutch. member carried by the arm 17 by means of aprojection 31 upon the operating-table. (See Fig. 15.) The position ofthe projection 31 is such that it will engage the arm 29 to throw theclutch members into engagement simultaneously with the lifting of thebottom, which is upon the support 16, as shown in Fig. 3. The clutchesare thrown into engagement as the supportis lifted,-this movementturning the arm 29 and turning the segment and slide to the rear of thereceptacle, as shown in Fig. 3. As the table position.

continues to revolve the cam upon the camshaft turns out of engagementwith the lever 20, the lever-arms turning back into position shown inFig. 17, bringing the receptacle-closing slide into contact with abottomwhich has been dropped and pushing it against the support, as shown inFig. 17. The connection between the segment and rod 28 consists of a pin32 upon the segment, which fits in a slot 33 in the rod and iscontrolled by a spring 34. This connection is provided for the reasonthat the bottom will be carried into contact with the side of thesupport before the support has reached its lowered This stops furthermovement of the segment, and the slot-and-pin connection allows the rodto return to its normal position, the spring 3; turning the segment andslide into closed position as soon as the support reaches full loweredposition, carrying the tile-bottom onto the top of the support.

The mechanism of the second step2'. e the feeding of the firstmixture-is illustrated best in Fig. 4. After a tile-bottom has beencarried into the mold, as shown in Fig. 3, the operating-table is movedone-seventh of a revolution by its actuating-cam 7. The mixture iscarried from a receptacle 35 by an endless carrier 36 to a hopper 37.The bottom of the hopper 37 is normally held closed by a slide-valve 39,connected by an arm 40 with the lever 41, said lever having pivotalsupport 42 upon the framework, with its lower end standing in positionto be actuated by a projection 43 upon the operating-table. Thelever-arm 4i is also connected with the valve 44, arranged in awater-pipe 45, so that as the lever-arm is actuated to withdraw theslide 39 it also opens the valve 44 and allows the filling of a chamber46. Below the hopperclosing slide 39 is aspace closed at its bottom byaslide 47. The slide 47 is operated in the same manner as the slide 39 byahinged leverarm 48, the lower end of which is adapted to be engaged bya projection 48%, as shown in Fig. 13. The lever 48 is connected with a'alve 49 in the water-pipe below the chamber 46, whereby as the lever isactuated to withdraw the slide 47 it simultaneously opens the valve 49and allows the water in the chamber 46 to pass to a second mixing-hopper50. A mixer 51 is arranged in the mixing-hopper 50. The mixers 38 and 51and the endless carriers are operated from the main driving-shaftthrough the medium of sprocketchains 90, sprockets 91, and gears. Theoperations just described have been completed before the operating-tablehas been turned to bring its mold underneath the funnel of themixing-hoppers. As the table is operated to bring its mold underneaththe funnel of said hoppers the slide 52, which closes the bottom of thesecond mixer, is drawn into open position-by the lever-arm 53 to allowthe mixture to pass to the mold, as shown in Fig. 14. The lever 53,which has hinged support in the framework, is actuated bya cam 54 uponthe cam-shaft. Said cam engages with a spur 55, carried by an arm56,connected with thelever, thus actuating the lever at the proper pointto open the second mixing-hopper, permitting the contents to drop intothe mold, the hopper valve being then closed by suitable springs. Atthis point the operating-table is turned one-seventh of arevolution,bringing the mold underneath the pressure head. (Shown in Fig. 5.) Thepressure-head 57 is secured upon the rods 58, slidably arranged inframework, as shown in Fig. 5, and held in raised position by springs59. The pressure-head is adapted to be forced into contact with themixture by a lever-arm 60, having fulcrum-support 61. The outer end ofthe leverarm is engaged byacam 62, carried by the cam-shaft, and theinner end bears against a plate (53, connected with the pressure-head bya coil-spring (34, said spring regulating the pressure upon the mixture.The head is preferably formed with a downwardly-projecting flange uponits outer edge. The above-described step having been completed, theoperating-table is turned through another oneseventh of a revolution,which brings the parts into the position shown in Fig. 6. In thisposition the mold stands underneath a series of hoppers, which convey tothe mold a second mixture, which forms the coating of the tile. Thehoppers with the actuating means correspond in construction with thehoppers and actuating means which supply the first mixture, andtherefore need not be so specifically described. The same numerals areapplied to these features as are applied to the corresponding featuresof the first mixing and feeding means, the character being added to thefigures to distinguish them from the numerals of the first combination.The second mixture having been supplied to the mold, the operatingtableis turned by its operating means underneath a second pressure-head, asshown in Fig. 7. The second pressure-head and its operating meanscorrespond with the first, except that the face of the pressure-head isnot flanged. As the pressure-head is withdrawn from the mold theoperating-table is turned by its operating means through anotherone-seventh of a revolution, which turns it into the position shown inFig. 8, bringing the mold underneath the troweling and scrapingmechanism. This consists of a scraper or troweler 65, eecentricallysecured to disks 66, mounted upon shafts 67. The shafts have sprocketconnection 68, and one of them is connected with the main drivingshaftthrough gears 69 and shaft 70, so as to be continuously operated. Thetroweler and its operating-shafts are mounted in a frame 71, slidableupon the framework, as shown in Fig. 8, and normally held in raisedposition by a spring 72. The frame 70 is adapted to be lowered to bringthe troweler into contact with the top of the mold by a lever 73, havingpivotal support 74 in the framework and connected at with thetrowel-frame, the outer end of the lever being engaged by a cam 76,carried by the cam-shaft. This cam engages with the lever when the moldis underneath thetrowel, as shown in Fig. 8. As this step is completedthe continued operation of. the operating-table brings the mold adjacentto an endless carrier 77. As the mold reaches this point a plunger 78,which is supported underneath the table and which stands flush with anopening in the fixed table 2, is forced upward, raising tliebottom andtile to a level with the carrier, as shown in Fig. 9. The plunger israised by a lever 79, which has pivotal support and is connected at itsopposite end by a rod 81 with a lever 82, the lever 82 having pivotalsupport 83. The inner end of the lever 82 is engaged by a cam 84; on thecamshaft, turning the lever upon its pivot and raising the plunger 78through the medium of the lever 79, the lever 79 having a slot-and-pinconnection85 with the plunger. As the plunger is raised to the positionshown in Fig. 9 the false bottom for the tile is engaged by a traveler86, which traveler is slidably supported upon a rod 87 and held in rearposition by a spring 88. The traveler is actuated by a cam 89 upon thecam-shaft to force the tile onto the endless carrier. The continuedoperation releases the lever 83, allowing the plunger to drop to thelowered position shown in Fig. 6.

The continued operation of the operatingtable brings it into position toreceive another bottom, when the operations above described are repeatedto continue the manufacture of tiles.
